This classic marine crane features a robust, welded steel box-section boom and a versatile hydraulic drive that supports all primary operations: hoisting, outreach adjustment, and slewing.
The crane design provides higher lifting capacity than folding boom and knuckle boom models. It also offers exceptional reliability and minimal maintenance requirements. This solution is optimal for applications where performance is paramount and sufficient operating clearance is available.
Model 3TX9M is designed for handling loads of up to 3 t and features a 9 m boom. Operational flexibility is provided by a local control station or a remote control pendant, connected via cable or radio link.

Marine Workhorse: How an Offshore Crane Operates in All Weather Conditions
Picture a port where operations never stop. Massive vessels discharge tons of containers, fishing boats land their catch, and naval craft prepare for departure. At the center of this activity stands a key piece of equipment without which a modern harbor is unthinkable: the offshore crane. But this is far more than just «a boom and a wire rope». It is a highly engineered machine designed to perform in conditions where the deck is constantly moving underfoot, and salt spray and Arctic cold are part of everyday operation. Let’s take a closer look inside one of these maritime workhorses and see how it is built.
The most obvious difference between an offshore crane and its land-based counterpart is the operating environment. Onshore, a crane is mounted on a rigid, stable foundation. At sea, everything changes. The vessel rolls with the waves, heels to one side, and may be exposed to severe storm conditions.
Engineers must design a system that remains fully operational under continuous list angles of up to 5°, while also withstanding extreme conditions when the vessel heels up to 15°. At the same time, wind speeds on deck can reach hurricane force. To perform reliably in such an environment, the crane must be not only robust but also intelligent — capable of adapting to external conditions and protecting itself from overload. The primary design objective is to ensure operational reliability and safety where the «ground» is never stable.
At the core of the crane is its steel structure. The primary components (column, housing, and boom) are fabricated from high-strength shipbuilding steel. This material is not only robust but specifically engineered to withstand continuous vibration and resist corrosion in harsh marine environments.
The crane features a modular design. The lower section, the column, is welded directly to the vessel’s deck. Inside the column is the hydraulic oil tank, effectively the crane’s circulatory system, with a capacity of 350 liters. Mounted on the column via a heavy-duty slewing system, the upper structure provides continuous 360° rotation. This is achieved despite the presence of multiple hydraulic lines and electrical cables routed through the system.
The crane housing is installed on top, with the boom hinged to the structure. Boom luffing is performed by a powerful hydraulic cylinder — a true «steel muscle» — allowing outreach variation from 1.5 to 9 meters. Lifting operations are handled by a winch equipped with a 57-meter steel wire rope and a hook block. The entire crane weighs over 5 tonnes, yet it is capable of lifting loads up to 3 tonnes, even under moderate sea conditions.
Hydraulics form the primary power system of the crane. Pressurized oil (up to 28 MPa — approximately 280 times the pressure in a car tire) drives all motions. System pressure is generated by two hydraulic power units (main and standby), powered by the vessel’s 380 V electrical network, with total power consumption up to 39 kW.
Why hydraulics instead of purely electric drives? Hydraulic systems provide smooth and precise speed control. The operator can lower the hook at speeds of up to 30 m/min without load, or carefully handle heavy cargo at approximately 18 m/min, avoiding dynamic shocks. Additionally, the hydraulic system is inherently fail-safe. In the event of power loss or engine shutdown, control valves automatically block oil flow, holding the load securely suspended without risk of dropping.
The most sophisticated components of the crane are its «brain» and sensory organs. Operation is performed by a single operator using joystick controls. Control can be executed either from a fixed control station on the service platform or via a portable remote control unit, similar to a compact backpack. This allows the operator to move freely on deck and maintain direct visual control of the load.
The crane is designed to prevent unsafe operator actions. This is ensured by an array of integrated sensors forming a comprehensive safety system.
All system faults are displayed on the control panel as error codes. For example, code «001» indicates low oil level, while «005» signals that the hook has reached the upper limit.
Engineers have also addressed emergency situations. The control panels feature large red «Emergency Stop» buttons that immediately de-energize the system. But what if the entire vessel loses power? For such cases, a manual hand pump is provided on the exterior of the column. By operating the pump lever, the operator can manually generate system pressure to safely lower the load or retract the boom into its stowed position.
The braking systems for both the slewing mechanism and the winch are redundant: if one fails, the second will hold the mechanism. This approach transforms a heavy machine into a predictable and reliable assistant that can be trusted even in harsh offshore conditions.
